An Ashland man who owned CultureWorks and now faces sexual abuse and drug charges continued to ply a teenage girl with marijuana in the weeks before his arrest, court documents claim.

Christopher Ian Iverson, 45, was arrested Friday on 28 counts that included third-degree rape, third-degree sodomy, third-degree sexual abuse, delivery of a controlled substance and endangering the welfare of a minor.

After his arrest, another person stepped forward over the weekend to provide additional information, said Ashland Police Department Deputy Chief Corey Falls.

A probable cause affidavit filed in court on Monday stated that Iverson, who was the owner of the shuttered Ashland cafe and performance venue in the Oak Street Plaza, allegedly delivered marijuana to a Medford teenage girl under the age of 18 on Dec. 21, 2013.

The affidavit stated Iverson allegedly engaged in sexual intercourse at least four times and oral sex at least once with the girl between Nov. 1, 2010, and Nov. 1, 2011, when she was under age 16.

During the same time period, he also allegedly engaged in sexual intercourse at least twice with another Medford teen when she was under age 18, according to the affidavit.

Iverson allegedly gave both teens MDMA at least twice during that time, the affidavit stated.

Police believe there may be more alleged victims. Investigators have no intention of arresting any minors involved, viewing them as victims in the case, according to APD.

Ashland police began investigating Iverson in early 2011. They received information that Iverson was allegedly providing marijuana, nitrous oxide and MDMA — an ingredient in the illegal drug Ecstasy — to minors in exchange for sexual activity. He also allegedly provided drugs to minors during events at CultureWorks and at other events in Oregon, according to APD.

Additionally, APD received information that Iverson was allegedly involved in a sexual relationship with one or more minor females who either worked at or frequented CultureWorks.

A break in the case came when multiple people recently stepped forward to provide information to investigators, Falls said.

Iverson remains in the Jackson County Jail, with bail set at $1 million.
